"The classic arch loop cap is great. It seems to seal the bottle more effectively. It would be nice to have more color options available."

"But falling apart very quickly"
"Personally I prefer to have a cap I can put in the dishwasher. The bamboo cap is cute, but I need products that can live the life I live. The bottle is near indestructible, now it has a cap to match!"
"The cap is nice and is easy to take on and off. Mine has a slightly different gasket than pictured, a more low profile black one, but it seems to work well and closes more flush than the others."
"My 7th grader decided he wanted to switch out his sports cap for this one - and he loves it! Durable and easy to use - no leaks if used correctly."
"Easy to carry with the loop"
